WILHELM FALKENBERG, OF NEW YORK, N. Y., ASSIG'NOR TO ALBERT WIELICH, OF

NEW YORK, N. Y.

PORTABLE HOT-WATER GENERATOR.

Application filed June 6,

To all whom it may concern:

Be it known that I, VVILHELM FALKEN- BERG, a citizen of Germany,residing at New York, county of New York, and State of New York, haveinvented certain new and useful Improvements in Portable Hot- WVaterGenerators, of which the following is a specification.

The present invention relates to improvements in portable electric hotwater generator or water heater for the instantaneous preparation of hotwater, and it is the principal object of my invention to provide anapparatus of this kind which can be conveniently carried along whiletraveling and which can readily be attached to any water supply faucetand electric socket.

Another object of the invention is the provision of an apparatus of thiskind embodying means for accelerating the heating process by producinga. diffusion of the water before the same is brought into engagementwith the heating body. v

A. further object of the invention is the provision of an apparatus ofthis kind which is equipped with novel means for dispensing the water inany quantity desired either in a permanent stream or in a succession ofstreams dispensed at intervals controlled by the user.

These and other objects of my invention will become more fully known asthe dcscription thereof proceeds, and will then be specifically pointedout in the appended claims.

In the accompanying drawing forming a material part of this disclosure,the single figure illustrates as an example the preferred form of myapparatus, it is to be understood however, that I do not wish to beconfined to the specific form illustrated, as many changes in thegeneral arrangement and in the construction of the minor details of myapparatus may be devised without deviating from the spirit and scope ofmy invention as defined in the appended claims.

My apparatus consists chiefly of a bipartite substantially globularglass or other casing 10, the halves of which are connected in anyconvenient manner, for instance as indicated at 11.

This casing has an upper neck 12 provided with inner thread and a lowerneck 13, also provided with inner thread. To the upper 1923. Serial No.643,747.

neck is attached a metal socket 14 or the like, provided with acircumferential groove 15 ending into a bead 16 adapted for engagementby the lower end of a rubber attachment or sleeve 17 allowing anattachment of the device to the lower end of a faucet, spigot or thelike of a source of water supply by means of a clamping band 18 of anywell known construction, the parts of which are united by a clampingscrew or the like 19. The socket 14 carries at its lower, shouldered end20 a sieve or nozzle 21; A heating coil 22 of any well knownconstruction is arranged within the casing 10 and one end of this coilis held and connected by means of a wire or conductor 23 with a plugcontact or the like 24, while the other end of the coil 22 is held andconnected by a wire 25 with the second contact 26.

To the threaded neck 13, a socket 27 is attached provided with anexternally threaded neck 28 for the attachment of a nut 29 equipped withan inner chamber 30 with which a plurality of outlets 31 arecommunicating. The lower end of socket 27 is formed with a seat 32 for aball valve 33 which normally is seated against the suitably shapedbottom wall of the chamber 30. Suitable washers are provided to make allthe connections watertight.

The operation of the device will be quite clear from the abovedescription; the rubber socket is connected at its lower end to the beadof socket 14: and its upper end is clamped to a faucet by means of clampband 18 and screw 19, the plug contacts 24, 26 are then connected in theusual manner by means of a cord to a socket of a source of electricityand the water from the faucet will be diffused by running through sieve21 and in this state will come in contact with the heating body or coil22 so that it is instantaneously "heated to any desired degree,whereupon it can be withdrawn through channels 31 by the propermanipulation of nut 29 operating the ball valve. \Vhen it is desired toclose the water exhaust openings, the nut is simply screwed home,allowing a convenient trans ter inlet at one end, a hot water outlet atthe opposite end, a heating coil arranged within the casing and havingits coils of gradually reduced diameter toward the hot water outlet, anda conically formed per foratedkiliffusing member arranged above the coiland underlying the inlet.

2. A hot water generator, comprising a two-part casing having a threadedneck in one part, a heating coil within the casing, a valve controlledoutlet leading from the casing, a socket having threaded connection withsaid neck, and a sieve carried by the lower end of the socket to ditfusethe water passing theretln'ough.

3. Electric hot water generator comprising a bipartite casing for thereception of a supply of cold water, a threaded neck on top of saidcasing, a beaded nipple adapt ed to be attached to said neck, a rubbersocket adapted to be attached to said socket, a clamp for clamping saidsocket to a faucet, a sieve attached to said socket for diffusing thewater, a heating coil within said casing, means for connecting saidheating coil with a source of electricity, and means for controlling thewater exhaust.

4-. Electric hot water generator comprising a bipartite casing for thereception of a supply of water, a means for providing a water-tightconnection between said casing and a faucet, a clamping means for saidconnection, a sieve for ditlusing the water entering said casing, aheating coil within said. casing below said sieve, wires for supportingthe ends of said coil within said casing, a pair of plug contacts towhich the ends of said wires are connected respectively for a connectionwith a source of electricity, a neck at the lower end oi said casing, athreaded socket secured to said neck, a chambered nut adapted to bescrewed upon said socket, valve seats in said chamber on nut and socket,a ball adapted to be seated on said seats, said nut provided with aplurality of water dispensing openings controlled by said ball.

In testimony whereof I have aft-zed my signature.
